A kind of head of extruding machine adjustable mold device
Technical field
The utility model relates to a kind of electric wire production equipment, especially a kind of adjusting device of head of extruding machine mould.
Background technology
Extruder, is extruder again, is the cable equipment that a kind of heart yearn being mainly used in electric wire is extruded, and its Main Function is that insulating materials is coated on plain conductor periphery, thus produces the electric wire of industry or life.For electric wire product, people pay close attention to its insulaion resistance, thickness of insulating layer and the degree of eccentricity (concentric circles).At present, the mould of overwhelming majority head of extruding machine mainly forms (as shown in Figure 3) by aligning external mold retainer 11, aligning retainer 12, aligning die sleeve 13, mold shell 14, interior die sleeve 15 and internal mold 16 etc., the mould of this structure in process of production, when will cause extrusion cable if slightly worn and torn, the degree of eccentricity of cable should not control, and easily causes insulation thickness bad, more mold exchange of having to, and the replacing of mould is too frequent, directly cause the increase of manufacturing cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of head of extruding machine adjustable mold device, the technical problem that the degree of eccentricity caused because using wearing and tearing to solve head of extruding machine mould should not control.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of head of extruding machine adjustable mold device, its formation comprises mold shell, internal mold, interior die sleeve, outer die casing and monochromatic die sleeve, die sleeve and internal mold junction are provided with internal mold tube connector in described, in the outside of outer die casing, outer die casing retainer is housed, outer die casing retainer is equipped with and can twists screw rod, in the outside of monochromatic die sleeve, tunable arrangement clamping ring is housed.
In above-mentioned head of extruding machine adjustable mold device, described outer die casing is equipped with external mold retainer.
Compared with prior art, the utility model has following beneficial effect: the utility model connects internal mold place at interior die sleeve increases by an internal mold tube connector, with fixing internal mold position, and increase outer die casing retainer and tunable arrangement clamping ring outward at outer die casing, monochromatic die sleeve, outer die casing retainer there are four can twist screw rod, can be used to the position regulating outer die casing and interior die sleeve, to reach the regulation and control to internal mold in head of extruding machine device and interior die sleeve position, thus reach the eccentric controlled object of insulating barrier.The utility model better can not only control head of extruding machine mould extrusion insulating barrier bias, the head of extruding machine mould extrusion insulating barrier degree of eccentricity is made to reach regulatable state, also make mould still can continue to use after slightly wearing and tearing, need not frequent more mold exchange, effectively reduce production cost.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A direction view of Fig. 1;
Fig. 3 is existing head of extruding machine mould structure schematic diagram.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Detailed description of the invention
Embodiment 1.As shown in Figure 1, comprise mold shell 1, internal mold 2, interior die sleeve 3, outer die casing 4 and monochromatic die sleeve 5, mold shell 1 is not damaged for the protection of monochromatic die sleeve 5, internal mold tube connector 6, internal mold 2 etc.Internal mold tube connector 6 is installed, with the position of fixing internal mold 2 at interior die sleeve 3 with internal mold 2 junction.In the outside of outer die casing 4, outer die casing retainer 7 is housed, in the outside of monochromatic die sleeve 5, tunable arrangement clamping ring 8 is housed, outer die casing retainer 7 is equipped with four and can twists screw rod 10 (as shown in Figure 2), the position of outer die casing 4 and interior die sleeve 3 can be used for regulating by twisting screw rod 10, to reach the regulation and control of internal mold in head of extruding machine device 2 with interior die sleeve 3 position, thus reach the eccentric controlled object of insulating barrier.External mold retainer 9 is also equipped with for fixing outer die casing 4, outer die casing 4.
Embodiment of the present utility model is not limited to above-described embodiment, and the various changes made under the prerequisite not departing from the utility model aim all belong within protection domain of the present utility model.
